GWT Button eventlistener designer

Question

For example I took html from a designer which is given below. How can i add click event which shows alert from GWT?

final Button button = new Button("OK"); I dont allow to add button dynamically from GWT by RootPanel.get("sendButtonContainer").add(button);

I am searching the syntax something like: RootPanel.get("sendButtonContainer").getWidget(0).addEventListener()??????? Jquery can search the button object from nameFieldContainer and dynamically add click event listener but is it possible in GWT??

You're looking for ClickHandler. Listeners were deprecated some time ago.

button.addClickHandler(new ClickHandler() {
  @Override
  public void onClick(ClickEvent event) {
    // do something...
  }
}

edit: I may have misunderstood your question. If you no longer have a reference to the button you could do

// code removed because it's really not the best way to solve this problem, and led to confusion...

But you'll have to be very sure that the element inherits from HasClickHandlers -- and you should really just keep a reference to the button, it's much cleaner that way.
